In less than a week NASA’s Deep Impact mission will collide with comet Tempel 1 with a 1 meter wide impactor at 23,000 mph after a voyage of 173 days and 431 million kilometers (268 million miles).

“The last 24 hours of the impactor’s life should provide the most spectacular data in the history of cometary science,” said Deep Impact Principal Investigator Dr. Michael A’Hearn of the University of Maryland, College Park. “With the information we receive after the impact, it will be a whole new ballgame. We know so little about the structure of cometary nuclei that almost every moment we expect to learn something new.”
